invezz'ibi I ac Ber/wwiz,

wri z, a citizen of the United States, and resident of Boston, in the county of Su'ifolk and State of Massachusetts, have invented new and useful Improvements in Meat- Racks, of which the following is a specifica- --tion. 'My invention relates to meat racks com prising essentially a plurality of uprights and a series of shelves supported thereby, the whole structure preferably being of metalliel formation throughout, and being readily separable for the purpose of cleansing orstoring the parts.

The invention consists in the improvei imirnn STATES PATENT OFFICE.

mentsf hereinafter described and pointed. out

n the claims.

Referring to the drawings which illustrate one embodiment of my; in e fifll r 1. isaside .ele'vationof a meat rack ration of the joint shown in Fig- 3; Fig. 6 is Intermediate brackets containing my invention; Fig 2 is an end elevat on of saidmeat rack; F g. 3 1s a per spectlve v1ew of an lnterlocking oint between one of the brackets and the corners of v the shelves; Fig. 4; is a plan view of the joint shown in Fig. 3; Fig. 5 is a front ele- .a ertical section of one of the joints shown Fig. 3; ig. 7 is a perspective View of one of the intermediate bracket for ppor ing,

the intermediate shelves; Fig. 8 is a front elevation of the bracket, and part of the shelf, shown in Fig. 7; and Fig. 9 is a plan view of one of said intermediate brackets.

The uprights of the rack are preferably made of piping and are shown .at A. a B, B, are shelves supported between the uprights A. I The rack is made in units comprising four uprights and the shelves therebetween, and

its capacity may be increased by adding similar unlts comprising a pair of additional uprights and shelves between them and the end pair of the adjacent unit.

C, C represent brackets mounted to sllde on the uprights A, A and are provided with set screws 0, a to hold them in any desired position of adjustment on theuprights. Brackets C, C are provided for the .upper and lower shelf and are 'madewith interlocking joint members cooperating with oint members on the corners of the upper and lower shelves to hold the frame rigidly 111 set-up position, as hereinafter described. D, D are also mount.-

made ,with a curved trough a open at the top and at both ends, and a post 0 within the curve of and partially surrounded by said trough as shown. Said trough tapers 1n. width-from the toptow ard the bottom.

' 4 The bracket 0 formed as above described constitutes the lower member of a ,locking joint between it and the corner of the shelf. When used at the outer corners of the frame, the bracke is mat an intermediate upright with-shelves at each side, it is made with a pair of such joint members, one .on each side, as shown in Figs. 3, 4 and 5. "The upper and lower shelves are provided with corner pieces E forming the upper joint member to interlock with the lower joint member formed on brackets C. The corner pieces E comprise the top plate e adapted to cover and reston. the top of the post .0 the curved web (2, depending from the top plate e, tapered and adapted to form a close fit with the curved and. tapered trough 0, and the angle extension members 6 The side and end bars of the shelves B with but one such joint member, a shown in Fig. 6. When used on are composed of angle-iron b. The surface of the top plate 6 and of the web 6' are elevated with relation to the surface of the extension members o to the extentof the thickness of the angle bars I), so that when the extension memherse are secured to the inner surfaces of the angle bars I; at their ends, the outer exposed surfaces of the angle bars and of the coriier pieceE are flush. The joint thus formed when the two members are interlocked constitutes a rigid connection between the uprights and the top and bottom shelves, readily separable when it is desired to knock-down the structure, and exposing few cracks and crevices to becomefouled by the accumulation 'of objectionable matter.

In order the more permanently to hold the bore 0 being countersunk at s to receive said nut.

The intermediate brackets D for supporting the intermediate shelves,ar'e provided with a ledge or support d and a vertical wall d to prevent the lateral dislodgment of the shelves. The intermediate shelves may be'merelyrectangular frames without any special coiner piecesuch as that used in' the top and bottom shelves, and rest loosely upon the supports (Z. The brackets D at the outer corners of the rack need be provided with only one ledge d (as shown in I "ig. 9); but when used upon the 'intermediate uprights with shelves at each side they rights, brackets thereon and shelves extending between the brackets, each upper and lower bracket having a trough on its upper side open atthe top and-at the ends and forming the lower member of aseparable joint, and each corner of *the upperfand lowershelves beingprovided with a downwardly extending web forming the upper member of such separable joint and adaptedto fit within said trough andthe joint thus formed between said members. being adapted -toprevent relative movement of .the' members When the latter are assembled.

2..A knock-down rack comprising uprights, brackets thereon and' shel ves'extend- 'ing 'betn' een the brackets, each upper and lower bracket having .onwits upper side a curved trough open at the top and at the ends, said-trough tapering in width from its -top toward itsbottom, forming the lower member of a separable oint, and each cor ner of the upper and lower shelves being provided with a downwardly-extending curved web tapered in thickness forming the upper member of such separable joint and adapted to fit within said curved and tapered trough and to form therewith a rigid but separable joint. j

33A knock-downrack comprising uprights, brackets and shelves, some of the brackets and the corners of the shelves supported thereby having separable joints therebetween, each joint comprising a lowerand an upper memberydhelower member being formed from the bracket with a curved trough open at the top and ends and tapered in width from the top toward the bottom, and a post partially surrounded by said trough, and the'upper member being formed at the corner of the shelf and comprising a.

top plate and a curved tapered "eb depending therefrom and adapted to fit into said trough, andaremovable bolt or screw passing through said top plate and said post to hold the upper and lower members of said joint together.-

t. In a knock-down rack of metallic formation, a plurality of uprights, brackets on saiduprights having a curved trough open at the top and ends and tapered in width from the top toward the bottom, and a postwithin the "curve of'said trough, a shelf comprising side and end angle bars, and corner.

pieces having an lemembers secured to the inner surfaces 0? said .side and end angle bars at their ends, a top plate at the corner adapted to cover the post of the bracket and projecting above the angle members flush with the upper surface of the side and end anglebars, and a curved web tapered in.

thickness depending from said top plate and adapted to fit into the trough of the bracket. Signed by .me at'Boston, Massachusetts,
